See Mars from Earth: this only happens every 15 years

On July 31, Mars will be 35.8 million miles from Earth, which is the closest it has been to Earth in 15 years.

What does this mean for sky watchers? It means that the red planet will appear super bright, and with its red-orange color, it will be difficult to overlook it in the night sky. From July 27 to 30, the point in the orbit of Mars will be closer to Earth, and will be closer to Earth before dawn, Eastern Time, July 31.

Mars may be Sighted by the human eye with the greatest clarity in the last 15 years from this midnight, thanks to the orbits of both planets that have made them to be at the closest point in this period, explained today the scientist of NASA Gerónimo Villanueva to EFE.

"Mars approaches the Earth every two years, but, at this moment, by its orbit it will approach much more than other times and we will see it very bright and bigger than usual", said Villanueva, Astronomer of Argentine origin working at the NASA Goddard Space Center

However, people will be able to see this "particular" event starting at midnight today from anywhere in the world.

"For this , they should look up at Lu na and, on your right, you can find a red-orange dot brighter than normal-Mars-and, at your side, another planet: Saturn, "explained the planetary scientist.

And if the sky is cloudy, ] You can watch it live here:

This astronomical phenomenon, it will happen again in 2033, occurs due to "relatively simple" circumstances, according to Villanueva.

Earth circles the sun every year (terrestrial) and Mars every two, so both planets line up and are closer than usual.

However, the orbit of Mars is "very eccentric", that is, there are times when it is farthest from the Sun and others closer, in comparison to the variation of the Earth.

Thus, the orbit of the red planet, one of the most irregular in the Solar System, and that of Earth are aligned with respect to the Sun in a synchronized manner every fifteen years. [19659012] From NASA, this occasion represents a great opportunity for researchers of the Hubble Space Telescope, which is operating "at its peak" since its launch in 1990.

"Hubble allows us to observe the Solar System and outside of it for a long time; It is a very complete information platform that helps us understand, for example, how climates change on different planets, "Villanueva said.

In the case of Mars, Hubble captured an image last week where see that the red planet is covered by a huge cloud of dust which has led to a "global storm" in that world.

That knowledge is "very important" for the space agency, which has a series of robots on the Martian surface to badyze that planet.

NASA, in fact, recently lost contact with the rover "Opportunity", which uses solar panels as an energy source.

Because of that documented dust storm by Hubble, "Opportunity" is not receiving the necessary sunlight to work and has entered into a state of hibernation until its panels are cleaned and the Martian atmosphere is cleared.

One of the major objectives of e all these investigations, without a doubt, is the arrival of man to Mars, the planet that these weeks can be clearly observed by millions of people from Earth.

This mission to Mars of "extremely complex logistics" would last for 3 years , because, with current technology, it takes 6 months to get there.

Once the astronaut reached Mars, the two planets would not be aligned, so you should wait two years for that window to open again of opportunity.

In addition to the 6 months of return, the NASA scientist recalled that a launch base would have to be built on Mars, a kind of Cape Canaveral on the Martian surface.

"We are working so that in a term of between 10 and 20 years we can send the first man or woman to Mars, "said Villanueva, who predicted that person" has not yet reached the university. "

That anonymous teenager, without knowing it, will be watching This midnight to Mars, the planet that will try to conquer in the coming decades.
